The cough and hesitation is likely too lean. It can also be caused from retarded timing, stuck distributor weights, or points out of adjustment.
To adjust the mixture, get it warmed up, adjust the idle mix first (the small screw on the side of the flange where the carb bolts to the intake). I believe that one adjusts backward, out is lean, in is rich. Lean it until it roughs up, then rich to best idle, then about 1/8 turn in more.
If the main is adjustable, bring the engine down to slow idle, then suddenly goose the throttle to full speed. It should accelerate without hesitation or coughing. Turn the main adjust (the larger screw) out to richen it. Try about 1/2 turn at a time, repeating the acceleration test until it takes throttle. A single puff of black smoke is desirable.
As for the throttle friction, not familiar with that specifically, but somewhere there should be a spring loaded friction clutch to hold the throttle lever in place. Some have a compensator spring also, but again, not sure on that model.
